ENGINE OIL REQUIREMENTS
FIRST OIL CHANGE. The engine oil in -
stalled in your car's engine at time of assem-
bly is high quality, " For Service MS" oil and
need not be removed until the first scheduled
oil change_ " Break-in" or " Flush-type" oils
are no longer required in your car's advanced-
design engine and must be avoided.
WHEN TO ADD OIL It is not unusual for
a new engine to use a certain amount of
engine oil during the break-in period. Check
oil level during each stop for gasoline. Add
oil only when level on dipstick is al or below
the "ADD OIL" mark.
WHEN TO CHANGE OIL Regul.,.
011
changes .,.e required to provide proper engine
operation.
Highway Driving, combined with some short
trip, slower speed operations extends the
38
effectiveness of the engine oil and permits
you to change 011 at 4,000 miles Intervals.
Short Trips (less than 10 miles) and slow
speeds, such as to the store, school, work
etc. and home again before the engine warms
up, causes harmful condensation and sludge
formation. This is typical of car operation in
city traffic. Driving under these conditions re-
quires that you change 011 every 3 months
regardless of mileage.
Severe Operating Conditions, such as fre-
quent driving on dusty roads, or in sandy
geographic areas, or unusually short trip
driving in cold weather may reasonably
require 011 changes more frequently than
every three months. Under these conditions,
consult and follow the advice of any Author-
ized Chrysler Motors Corporation Dealer's
Service Manager.
